Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of micro-channel aluminum flat tube production, in particular to a cutting equipment for micro-channel aluminum flat tube production. BACKGROUND

[0002] The core function of the micro-channel aluminum flat tube cutting machine is to achieve precise length cutting of aluminum flat tubes. The equipment is mainly composed of a cutting base, a processing table, a cutting assembly, and a scrap collecting system. The processing table is fixed at the top end of the cutting base, and the table is provided with sliding rails for the sliding of the cutting assembly. The inside is equipped with multiple sets of positioning plates for symmetrically placing aluminum flat tubes. The multiple sets of positioning plates support batch clamping of aluminum flat tubes. The cutting assembly realizes stable displacement through the sliding rails, ensuring the flatness of the cut to meet the stringent requirements of micro-channel pipe fittings on size tolerance. Some high-end models also integrate hydraulic fixing devices. The electric push rod drives the clamping plate to hold the pipe, further preventing pipe deviation caused by cutting vibration. It is widely used in the fields of automobile air conditioning, commercial heat exchange systems, etc. Its compact structure and automation characteristics significantly reduce the time and labor cost in aluminum flat tube processing.

[0003] A micro-channel aluminum flat tube cutting machine is disclosed in Chinese Patent No. CN222058976U. The cutting assembly is started by the control panel to cut the micro-channel aluminum flat tube. At the same time, the dust collection fan is started by the control panel. The cutting assembly cuts the micro-channel aluminum flat tube and generates debris that falls into the collection hopper through the falling groove. The dust collection fan generates wind power when it is working, which sucks the debris in the collection hopper into the collection cabinet through the dust collection pipeline. The collection assembly can timely and conveniently absorb the debris generated during cutting by the cutting assembly, reduce the accumulation of debris on the processing table, and increase the processing efficiency of the cutting assembly.

DETAILED DESCRIPTION

[0022] In order to make the technical means, technical features, purposes and effects realized by the present application easy to understand, the present application is further described below in combination with specific embodiments.

[0023] Embodiment: The cutting equipment for micro-channel aluminum flat tube production described in the present application comprises a feeding assembly 1 and a transverse cutting machine 2 arranged inside the feeding assembly 1, and the inner side of the transverse cutting machine 2 is drivingly connected with a cutter 4.

[0024] In the present embodiment, the feeding assembly 1 comprises pneumatic or hydraulic clamping blocks arranged before and after the cutting zone (the area where the transverse cutting machine 2 moves), the clamping block before the cutting zone fixes the pipe, and the clamping block after the cutting zone pulls the pipe at a uniform speed in the rear direction (X-axis direction) to break the pipe, thereby reducing the folding of the cut part by using the toughness of the remaining 20% uncut part to break, which is the prior art and will not be described in detail here; the transverse cutting machine 2 adopts an upper and lower symmetrical double-disc cutter 4 (divided into an upper cutter and a lower cutter), which realizes bidirectional cutting by synchronous rotation, the cutter moves horizontally along the width direction (Y-axis) of the aluminum flat tube through a slide rail, thereby ensuring that the cutting track is perpendicular to the pipe, and the cutter 4 maintains a fixed angle (usually perpendicular to the pipe surface) during the cutting process to avoid deformation caused by rotation and extrusion; the core of the cutting process of the transverse cutting machine 2 is to replace the traditional full-face cutting by precise depth control cutting + mechanical pull-off, thereby maximizing the integrity of the micro-channel structure, the transverse cutting machine 2 controls the cutter 4 to move along the Y-axis from one side of the aluminum flat tube to the other side, the upper cutter cuts downward from the upper surface to 80% of the wall thickness to form an "upper cutter seam" that does not penetrate through, the lower cutter cuts upward from the lower surface to 80% of the wall thickness to form a "lower cutter seam", and the rear clamping part pulls the pipe at a uniform speed in the rear direction (X-axis direction) to break the pipe, and then the cutting direction is alternately cut to circulate.

[0025] Specifically, the air pipe 9 is fixedly connected to the base 3 near the cutter 4, the air pipe 9 is fixed with an air nozzle 91 near the cutter 4, the base 3 is fixed with a baffle 92 near the cutter 4, and the air outlet direction of the air nozzle 91 is tangent to the outer side of the cutter 4.

[0026] In this embodiment, before using the device, the staff first connects the external compressor with the air pipe 9, then connects the connecting pipe 86 with the external coolant storage device, opens the air inlet valve of the compressor to suck in the ambient air, then reduces the volume of the gas through a mechanical device (piston, screw rod, etc.) to increase the pressure, finally inputs the high-pressure air into the air pipe 9 through the air outlet valve, and the high-pressure air is sprayed to the surface of the cutter 4 through the air nozzle 91 under the guidance of the air pipe 9 to clean the surface of the cutter 4. Since the rotation direction of the cutter 4 is opposite to the spraying direction of the high-pressure air, the cleaning effect of the high-pressure air on the cutter 4 is further increased.

[0027] Specifically, the inner side of the transverse cutting machine 2 is provided with the oil pipe 5, the outer side of the oil pipe 5 is fixed with the mechanical linkage part 7, one side of the mechanical linkage part 7 is connected with the cooling plate 8, the outer side of the cutter 4 is provided with the air pipe 9 for blowing the cutter 4, and the inner side of the feeding assembly 1 is fixed with the clamping block 10; the mechanical linkage part 7 is connected with the movable plate 6 through sliding clamping on the outer side of the oil pipe 5, the inner side of the movable plate 6 is rotationally connected with the pneumatic valve 71, and the pneumatic valve 71 cooperates with the clamping block 10 to stretch the oil pipe 5 to supplement the coolant and close the cooling plate 8 when the transverse cutting machine 2 moves; the oil pipe 5 is used for conveying the external coolant to the coating part 81 through the feeding groove 84 and the feeding hole provided in the inner side of the cooling plate 8, the coating part 81 applies the coolant to the surface of the cutter 4, and after the cutter 4 rotates out of the inner side of the cooling plate 8, the coolant is evaporated by cooperating with the airflow to increase the cooling rate by using the latent heat of vaporization, the oil pipe 5 is fixed to the inner side of the transverse cutting machine 2, the inner side of the transverse cutting machine 2 is fixed with the base 3, the base 3 is located on one side of the oil pipe 5, one side of the movable plate 6 is fixed with the elastic part, the elastic part can be a spring or other device capable of providing radial elastic force, and the other end of the elastic part is fixedly connected with the input end of the oil pipe 5.

The ball changes the sliding friction of the pneumatic valve 71 with the clamping block 10 to rolling friction, which improves the service life of the pneumatic valve 71. The restriction on the movable plate 6 is removed, and the movable plate 6 is pressed against the oil pipe 5 under the contraction force of the elastic member. The internal space of the oil pipe 5 is reduced, and the coolant enters the feed groove 84 through the connecting pipe 86 and the one-way valve for connecting the connecting pipe 86 and the cooling plate 8 under the action of pressure. Then, after being divided through the discharge hole 85, the coolant infiltrates the coating member 81. When the cutter 4 rotates and passes through the coating member 81, the coolant is evenly applied to the surface of the cutter 4. After the cutter 4 moves out of the coverage range of the coating member 81, the coolant on the surface of the cutter 4 is accelerated to evaporate under the blowing of compressed air. The latent heat of vaporization is used to improve the cooling rate, and the amount of coolant is reduced by more than 70% compared with immersion cooling. If the temperature of the cutter 4 drops below the required temperature, when the movable plate 6 contacts the input end of the oil pipe 5, the rotation speed and moving speed of the cutter 4 are restored. If the temperature of the cutter 4 does not drop to the required temperature, the oil pipe 5 is stretched again to supplement the coolant before the clamping column 73 moves to the inside of the inclined slot of the bottom plate 74.
